For Windows users, Google Picasa is the best and easiest to use photo software ever written, and it is free. It organises your photos; it can adjust exposure and colour, straighten a skewed horizon, crop and resize. It can even do retouching and apply special effects. If you do manage to make a mistake with it, you can always ‘Undo’ at the touch of a button – the original files are always preserved. Only a professional photographer would require more. Most people don’t need anything as complicated as Adobe PhotoShop and find it confusing.
Google Picasa is available as a free download here: http://picasa.google.com/. It is a small download (14.6MB) and installs in a couple of minutes.
Picasa is also available for the Mac, but Mac users already have iPhoto, which is very similar.
